May I offer a small suggestion? I really think you should remove the assasin guild (or change it's properties so it gives a slightly higher kill plot power or maybe make the assasin into guard against assasination), Why am I suggesting this. After playing 250 years in multiple games (using either ck+ and hip - ck+ just removes the custom potraits and hip without the potrait module and both works fine) it's basically gets a killing field since anyone who doesn't like you (and have an assasine guild -which most of them have at that point) or any other character and is close assasinates you (and since assasines are almost sure hits (i haven't had a hit against me fail so far )). For example in one game i had 5 consecutive assasinations on my characters in less than 4 years (some probably from my own vassals). It also happens on npc characters so regurarly it became stupid at some point. It's not even cheating it's negative opinion + money = assasination. EDIT: Or another suggestion is make the target with assasin into a more likely to fail (for example only 20% success rate with the added bonus that you don't get discovered unlike the plot to kill command) making it more fair game.
